Great product - I've been using Xampp for years but recently run into a problem I can't solve..

I've installed Apache 2.2.2 from xampp-win32-1.5.3a-installer.exe on a new Windows 2003 Server (5.2 Build 3790 Platform 2 Service Pack 2) but if pages of the PHP website it is running are requested too fast (by clicking on the href links fast) the Apache server sometimes crashes (about 3 times a day).
